try some jazz.. listen to frank gambale, guthrie govan, shawn lane, larry carlton.. great great musicians..
Seriously listen to 'Take that' ....its the most awesome pop band today....they used to be a boy band back when robbie williams was with the group...they're a man band now..
dude u should seriously listen to PUNK rock. it's excellent. Sum 41, greenday, the offspring- this bands are great. specially Sum 41. hear their song i'm sure u will love it.
Try some indian classical music as well. Man those ragas are some shit. I am in love with how they sing Kurukshetra shlokas. Its in E. Perfect metal!
Listen to Eric Serra's compositions. Particularly the Leon movie soundtrack. David Gray and Ben harper are two others i recommend. Toad the Wet sprocket deserves a listen as well.
